2015.5-2016 6.6L Duramax LML 4" DPF & CAT Delete Pipe & EGR Cooler Delete Kit

Constructed from heavy-duty T-409 stainless steel to deliver exceptional heat resistance, structural durability, and reliable protection against rust and corrosion.

Features smooth 4-inch mandrel-bent piping designed with the correct 3-bolt turbo flange (specifically for 2015.5–2016 LML models) to maintain high exhaust velocity and faster turbo spool-up.

Completely eliminates the restrictive factory DPF and catalytic canisters to stop fuel-draining active regeneration cycles and significantly lower operating EGTs.

Removes the factory EGR cooler and valve components to prevent harmful exhaust soot from choking your intake manifold and eliminate internal coolant leak risks.

Bundles critical exhaust and emissions modifications into a single comprehensive installation to save repeated teardown labor around the tight rear engine compartment.

Engineered precisely for 2015.5 through 2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L LML Duramax diesel engine (Features 3-bolt flange; does not fit 2011–2015.5 V-band clamp models).
